1. Introduction
These Application Notes describe the configuration of a Voice over IP (VoIP) solution using ProCurve 5400, 3500 and 2600 Series Switches by HP connected to an Avaya Communication Manager, Avaya SIP Enablement Services, Avaya Modular Messaging and Avaya IA770 INTUITY AUDIX. Compliance testing emphasis was placed on verifying the prioritization of VoIP traffic and voice quality in a converged VoIP and data network scenario. Quality of Service (QoS) based on Layer 2 Priority (802.1p) and Layer 3 Differentiated Services (Diffserv) was implemented across the network to prioritize voice traffic over the LAN. The Avaya IP Telephones get QoS priority settings from Avaya Communication Manager and are enforced in the network by the ProCurve Switches. To verify VoIP traffic was given priority over data traffic tests were performed by over subscribing the LAN interfaces with low priority data traffic and verifying that acceptable voice quality was achieved when calls were routed over all of the LAN interfaces. Compliance testing included QoS, throughput, link aggregation, rapid spanning tree, load balancing, Open Shortest Path First (OSPF), Direct IP Media connectivity and the G.711 and G.729 codecs.

2. Hardware Configuration
The configuration in Figure 1 shows a single site converged VoIP and data network with multiple closets and labs configured with link aggregation, rapid spanning tree, load balancing and OSPF.
For compliance testing, a centralized corporate DHCP server was used. To better manage the different traffic types, the voice and data traffic were separated onto different VLANs.
